The government has finally realeased details of the Melbourne metro plan, analysis as follows:
An interchange or provision for an interchange should be provided at Lloyd street for connection with the Upfield and Cragieburn lines. This is currently not included in the plan.
The Arden metro should be located adjacent to Abbotsford st and Queensberry st to provide connections with the 57 West Maribynong tram. The Arden metro will likely see high rises spring up in North Melbourne. The government and local councils should work in concert to protect Errol St and heritage buildings in the area.
Consideration should be given to a new tram line servicing Docklands via the Arden metro to fully activate the North Melbourne Area. Connections to multiple tram line is essential to create a "CBD" type concentration.
The placement of the Parkville metro is excellent. It services the hospitals, university and research hubs in the area. Further it has excellent connections to tram lines down Flemington rd and Royal parade.
Consideration should be given to the effects of tram patronage once the Parkville metro opens. Should trams continue to terminate at the university or should a new terminus, perhaps at Docklands be used? It should be noted that this plan doesn't solve or address the Docklands blackspot.
I believe the location of the North and South CBD metros are appropriate and pragmatic. They take into account trains that travel through the loop and those that run direct to Flinders st. There will be those that a dissapointed that the new metro doesn't tread new ground. Perhaps with a stop that is not already well serviced, say Lygon St, though it's understandable that costs are kept manageable.
Lastly, I agree with the reasoning in the placement of the Domain metro. It will act to reduce peak loads on trams down St Kilda rd which should be commended.
